FOR IMMEDIATE RELEASE


           POLYONE TO SELL ELASTOMERS & PERFORMANCE ADDITIVES BUSINESS
                    TO LION CHEMICAL CAPITAL AND ACI CAPITAL

CLEVELAND - June 29, 2004 - PolyOne Corporation (NYSE: POL) announced today that
it has signed a definitive agreement to sell its Elastomers and Performance
Additives business to an entity formed by an investor group led by Lion Chemical
Capital LLC and ACI Capital Co., Inc.

The purchase agreement provides that PolyOne will receive gross proceeds before
associated fees and costs of approximately $120 million, of which $106 million
will be paid in cash and $14 million in the form of a note from the buyer. This
price is within the range of estimates that PolyOne had anticipated for the sale
of the Elastomers unit.

The transaction, which is expected to close in the third quarter, is subject to
customary closing conditions and the buyers' receipt of their financing.

The Elastomers and Performance Additives business is a leading merchant provider
of customized, high-performance elastomer materials and additives for use in
diverse end markets, including the transportation, electrical, industrial and
printing industries. Headquartered in Solon, Ohio, the group operates five
manufacturing facilities in the United States and one each in Mexico and the
United Kingdom. Its first rubber compounding facility in China is slated to open
near Shanghai later this year. Revenues for the four quarters ended March 31,
2004, were $349 million, which represents 13.5 percent of PolyOne's total sales
from both its continuing and discontinued operations during that period.

"This action represents significant progress toward our announced goals to focus
on our businesses with the greatest synergy and to improve our balance sheet,"
said Thomas A. Waltermire, president and chief executive officer. "Our
Elastomers business unit is the largest of the businesses we targeted for
divestment late last year. We are satisfied we have negotiated a fair value, and
we plan to apply the proceeds to debt reduction."

"This business has the capacity and proven capability to grow, and we are
committed to its success," said Peter De Leeuw, managing director of Lion
Chemical and the prospective chairman of the new company. "We anticipate no
immediate change in business practices of the Elastomers unit, and no effect on
Elastomers customers, suppliers or employees. The unit's current management
team, headed by PolyOne Vice President and General Manager John E.
Quinn, will remain in place."



Added Ezra Field, a managing director of ACI Capital, "We are excited to have
the opportunity to make this investment, and we look forward to a successful
partnership with the company's management. We believe we are acquiring a
market-leading business at an attractive point in the business cycle."

PolyOne announced last October that, as part of its efforts to improve
profitability and strengthen its balance sheet, it would confine its strategic
emphasis to its Plastics Compounding, Color and Additives Masterbatch, and
Distribution businesses. These businesses have leading market positions, and
most of them are global in scope.

In line with this goal, PolyOne announced that it would divest its Elastomers
and Performance Additives, Engineered Films and Specialty Resins businesses. As
a result, the Company began reporting these business units as discontinued
operations in the fourth quarter of 2003. PolyOne has stated that it expects to
complete all three dispositions in 2004. The pending Elastomers divestment is
the first such disposition.
